Motivair is a world-class supplier of water
chillers for industrial process cooling and
specialty HVAC systems. The MPC chillers
offer an unparalleled range of cooling
capacities, and available options that allow
customers to select a chiller best suited to
their needs. Designed with three goals in
mind; reliability, flexibility and ease of use,
the MPC range of water chillers have earned
a quality reputation, trusted around the
world to provide reliable cooling for critical
process applications.
RElIAbIlITyThe MPC range of chillers is
manufactured using the highest quality
components. All components must
pass a rigorous test cycle before being
selected for production use. All fan &
pump motors are TEFC or TEAO, and
are therefore suitable for outside use.
All electrical components are UL and
CSA listed. MPC chillers are CE
certified, and are also certified by ETL
to be in compliance with UL 1995
and CSA C22.2 standards. The
combination of innovative design,
premium components, and universal
certification yields a final product
worthy of the most demanding cooling
applications.

flExIbIlITyProcess cooling and HVAC heat
loads often change throughout the
workday. The MPC range features a
unique “CYCLING” design that allows
the chiller to adapt automatically to
any heat load from zero to 100% of its
capacity. This cycling design utilizes a
large storage reservoir, to insure close
water temperature control regardless
of the load, or the load change. The
MPC evaporators are NOT immersed
in the reservoir, and are therefore
readily accessible for service, repair or
replacement. The reservoir also acts
as a buffer against temporary surge
loads. Substantial energy savings can
be achieved during low load chiller
operation. MPC chillers do not utilize a
hot gas bypass valve, common to other
chillers, because these valves create
an artificial heat load, which requires
the chiller to operate when the load
is reduced. The unique MPC cycling
design also allows it to be used on
multiple processes in a single building.

THe MICroProCeSSorThe standard Motivair microprocessor
controller is a very powerful, yet user-
friendly device. It offers a wide range
of standard controls and alarms to suit
any chiller application. It can control
up to 4 stages of cooling in the chiller.
Optional communication features
include a serial card connection to a
remote PC and a full-feature, remote
wall-mounting controller, connected via
an RS485 cable up to 500 feet away.
For those applications requiring up to
8 cooling stages, and/or a higher level
of remote communication, the PC02
advanced PLC system is available from
the MPC 2200 and above.

MPC InduSTRIAl WATER CHIllERSThe MPC chillers can be applied to a
wide range of industrial and commercial
applications. Some common
applications for MPC chillers include:
oncology Machines

industRial and CoMMeRCial aPPliCations
DyNAMIC eNergy SAVINgSThe Motivair MPC chillers all contain
an oversized thermal storage reservoir.
This unique feature allows the chiller to
cycle its compressor(s) and fan(s) off
during reduced process loads, while
the pump runs continuously. This will
maintain water temperatures within +/-
3°F of set point. Competitive chillers
typically use a hot gas by-pass valve
to balance the chiller capacity against
reduced loads, therefore wasting energy
and causing unnecessary wear and
tear on the chiller.

THE ulTIMATE SoluTIon foR oPTIMAl EnERgy SAVIngSThe Motivair MPC-FC chillers with “Free-Cooling”
capability are designed to provide the owner with
optimal performance, year round, in varying ambient
temperatures. This “Free-Cooling” option, available on
models MPC 2200-7200 is supplied complete with
pump and storage reservoir, “Free-Cooling” coil and
the PCO2 advanced PLC control package – a unique
single package for year-round energy savings.
The refrigeration plant is designed to cool the
designated heat load during the highest summer
temperatures. When ambient temperatures fall
overnight or during cooler seasonal weather, the
integrated “Free-Cooling” system is automatically
activated. The system operates by directing the
return chilled glycol through the “Free-Cooling” coil,
before it enters the evaporator. This is achieved via
an automatic motorized valve, controlled by the PLC,
whenever the ambient falls below the return
chilled glycol temperature set point. The glycol
is either partially or completely cooled in the “Free-
Cooling” coil for maximum energy savings. As a result,
less mechanical refrigeration is required to achieve
the chilled glycol set point, and the refrigeration
compressors are cycled off by the PLC, which
continuously monitors the system.
Energy savings in areas with cooler winter months
are substantial. Wear and tear on chiller components
is dramatically reduced, due to fewer running hours
during winter months. Automatic switching between
mechanical cooling and “Free-Cooling” allows for
optimal performance year round. As a general rule of
thumb, “Free-Cooling” savings more than pay for the
initial investment in the first year of operation!
